Circulating soluble low-density lipoprotein receptor-related protein 1 (sLRP1) concentration is associated with hypercholesterolemia: A new potential biomarker for atherosclerosis.

Int. J. Cardiol.. 2015 Dec;201:20-9, PMID: 26285183

There is clinical interest in identifying novel lipid biomarkers for evaluating cardiovascular risk and targeting lipid-lowering treatment. Low-density lipoprotein receptor-related protein 1 (LRP1) plays a crucial role in the dysregulated cholesterol transfer from modified lipoproteins to human coronary vascular smooth muscle cells (hVSMCs), promoting hVSMC-derived foam cell formation. LRP1 has a soluble and circulating form (sLRP1) generated from LRP1. Cholesterol modulates the release of the soluble form of LRP1. Using in vitro, ex vivo and patient-based approaches, we tested the association between circulating sLRP1 concentrations and hypercholesterolemia and the potential of sLRP1 as a biomarker of atherosclerosis.
